Insert new row into table 13 as follows:

Table 13—Authentication frame body

Order / Information / Notes
x / Collocated BSS Element / The Collocated BSS element may be present if dot11CollocatedBssEnabled is true.

Insert new row into table 14 as follows:

Table 14—Deauthentication frame body

Order / Information / Notes
x / Collocated BSS Element / The Collocated BSS element may be present if dot11CollocatedBssEnabled is true.
7.2.3.12 Action frame format

Insert new row into table 15 as follows:

Table 15—Action frame body

Order / Information / Notes
x / Collocated BSS Element / The Collocated BSS element may be present if dot11CollocatedBssEnabled is true.
.

Insert the following new clauses:

7.3.2.x Collocated BSS element

The format of the Collocated BSS element is shown in Figure v1.

Element ID / Length / Root BSSID / Radio
Number / Antenna
Number / Flags
Octets: / 1 / 1 / 6 / 1 / 1 / 1

Figure v1—Collocated BSS element format

The Element ID field is equal to the Collocated BSS value in Table 20.

The value of Length field is 11 octets.

The Root BSSID is the BSSID the AP has designated to track all Collocated BSSs with. The Root BSSID must be one of the BSSIDs that the AP advertises, that the BSS using that BSSID must advertise this IE. All frames with this IE that share the same Root BSSID must be transmitted on the same channel and must not differ in Radio Number across advertisements, as a part of normal operation.

The Radio Number is an arbitrary value, from 0 to 255, representing the radio. APs should advertise different Radio Numbers from different radios on the same AP. The AP shall not advertise different Radio Numbers for the same Root BSSID, as a part of normal operation. The value 0 is taken to mean that the frame is coming from the first radio.

The Antenna Number is an arbitrary value, from 0 to 255, representing the antenna from which the frame was transmitted. The value 255 is taken as unknown. The value 0 is taken to mean that the frame is transmitted from the same antenna that beacons for the BSS are transmitted.

The Flags field is a bit field with the following bits defined.

Reserved
Bit: / 0-7
